my dh's parents live 5 hours away and v soon we have to make the long trek up there. last time we went my dd (now 16 months) had an absolute nightmare (so did we!) she only slept for about an hour the entire trip and screamed the rest- we even went at night! a friend of mine who is a pharmacy dispenser reccommended we give phenigan to help her sleep but im in two minds- anyone else used it and if so how was it/any side effects etc?
